I LOOP-WINDING MACHINE.

Application filed February 10, 1925. Serial No.-. 8,282.

Greneri-cally this invention relates towinding or reeling machines, butit more. especially comprehends the type adaptable'for windingloops,-reeling wire, winding field coils, transformer coils,-and thelike.

' One objectof this invention is to provide a winding machine embodyinga novel type of rigid winding head bar graduated. to facilitate anaccurate set-up for length of loop and designed to eliminate possiblevariations inloop lengths where a plurality of loops arewound at onesetting.

Another object of this invention is to design a winding machineembodyinga rigid winding head bar provided withad-justable means forforming varied width loops, means for releasing the tensiononthecompleted loop, and-additional means instantly -detachable tofacilitate removal of the loop from the winding pins. 7

Still another object of this invention is the provision of a machine of:the above character embodying a clamping block means associated withthe windinghead bar for holding the starting lead wires, eliminating anywastage of wire, and placing inside lead wire or wires incorrectposition for finished loop.

A further'object of this invention is the provision of a winding machineof the above thedrive or high speed shaft for facilitating the rapidwinding of field coils and for transferring wire from large to smallreels.

lVith these and other objects in view, which will become apparent as thedescription proceeds, the invention resides in the construction,combination and arrangement of parts, hereinafter more fully describedand claimed, and illustrated in the accompanying drawings,'in which likecharacters of reference indicate like parts throughout 7theseveralfigures, of which:

tory, in that, they were eitherv not accurate 1I1 theividth or length ofthe loops, or the finished loop was diflicult .to remove, or theIleadwires could not be expeditiously held in .place, and it .wastoovercome the deficienciesof such devices and to provide a windingmachine. and Windinghead comprehending novel. and improved featuresembodying means for perfectly controlling the device, rigid winding headbar, lead clamping trigger-block, variable speed shafts, and surpluspower on winding head shaft through special gearing interconnecting thesaid shafts, and other features that will be more fully explained. asthe description proceeds.

that I evolved .the loop winding. machine forming the subj ect. matterof this invention.

In the illustrated embodiment characterizing this invention thereis.shown a frame 1 .formed with cross bars 2 adapted to. support-bearings3 in which isjournaled power 9 is a left end elevation of Fig.8;

IOU

shaft 4 carrying a-plurality of ratioed pulleys 5, 6, and 7. The saidframe 1 isformed with integral upper cross bars 8 adapted to supportsuitable bearings in which. are mounted the power or high speed shaft 9,intermediate or gearing shaft 10 and.low speed or Winding head shaft 11.Loosely mounted-on the drive shaft 9 intermediate the bars-dare thepulleys 12, 13, and .14,

ratioediinversely to the lower pulleys'5, 6,

and 7, the outer face of the said pulley 14 is adapted to enga e theinner'surface of, brake drum 23 suitably secured to frame bar 8 whenmember 18- is moved to braking position. The hub 19 is centrallyrecessed as at 24 to receive the. fingers of the U- shaped clutch fork25 which is secured to a horizontal pin 25 by means of set screws 25.The said pin passes through holes in the two lugs 25 formed onhorizontal plug member 25 which connects the prime memher 1 together atthe top just under the hood. The right hand end of pin 25 is beveled forcontact with the complement-a1 beveled surface 25 at the upper end ofconnecting rod 27, the lower end of said rod being hingedly connected toarm 28 secured to the inner end of pedal rod 29 j ournaled through thelower extremity of frame 1 and provided at its outer end with pedal 30.Thus when stepping on pedal 30, the rod 27 is moved verticallycontacting the bevel surfaces in a wedging action which forces theclutch fork 25 to the left bringing surface 16 of clutch A in contactwith the cone pulley 14 to transmit driving power to shaft 9 .andthrough the train of gears to rear shaft 11. The clutch fork 25 isconnected intermediate its length to frame 8 by coil spring 26 whichnormally holds surface 22 in contact with the inner surface of brakedrum 23, which serves to lock the machine in normal position andprevents it from backing up and slacking up on the wires which are beingwound into a loop on the winding head.

One end of shaft 9 extends through the casing 31 to which may be secureda reeling attachment (not shown) for winding field coils and fortransferring wire from large to small reels and the like. Mounted on theother end-of shaft 9 adjacent pulley 12 is the small gear 32 adaptedto'mesh with the large gear 33 secured to shaft 10, which also carriesadjacent gear 33 small gear 34 adapted to mesh with large gear 35mounted on winding head shaft 11, one end of which extends through thecasing 31 and beyond the frame member 8, and externally threaded toengage the internally threaded hub member 36 of the winding head.

The outer end of hub 36 is apertured to receive the headbar 37 firmlysecured therein by cap; screw or pin 38 which passes through said huband head bar and which also serves to secure slotted adjustable plate 39carrying pin 40 to which the ends of the wiresmay be fastened whenstarting to wind a loop, in case the lead wire clamping trigger'blockhereinafter described is not'emsaid bar. Slidably mountedon the saidhead 7 bar 37 on each side of the hub 36 arethe winding pin blocks 42provided with winding pins 43 threadedly or otherwise suitably securedtherein and externally; threaded to engage the internally threadedadjustable nuts 44. s V r The trigger-block 45 embodies a pair of spacedcircular plate, members joined by an eccentric segmental hub section 46and a trigger member 47 adapted for insertion between the plates andpivotedly mounted therebetweenby a pin passing through apertures 48 inthe plateinembers and 49 in the trigger 47,. A compression spring 50 ismounted on the pin 50 and adapted to seat against the trigger and thehub 46 to normally maintain the notch 51 in engagement with an annulargroove formed in the pin 43 predeterminedly spaced from the adjust ablenut44. The said trigger-block 45 may be detached from the winding pin 43by depressing the free end of trigger 47 disengaging the notch 51 fromthe groove.

The winding pin blocks 42 are provided at their rear ends withprojections 42 suitably secured thereto and on which are adapted to befastened extension arms 52 with their upper ends apertured to receiveextension pin blocks 53 secured thereto by nuts 54, the outer ends ofblocks 53 carrying winding pins 43, adjusting nuts 44 and trigger blocks45' exactly as heretofore described in connection with the pinblocks 42,these extensions being provided for use where it is desired to wind oddshaped coils.

Oneside of the winding head bar 37 is graduated on each side of the hub36, as'at 55, so that the winding pin blocks 42 may be accuratelyadjusted to provide loops of varying lengths, and. they are firmlysecured on said bar 37 by clamping members 56 positioned adjacentsaidblocks and connected thereto by bolts 57 carried by said members 56and adapted to threadedly engage the blocks 42, the said. clampingmembers being secured to the bar 37 at any desired points by bolts 58.

In order to expedite the removal of the finished loop 59-fro1n'thewinding pins 43 it. is advisable to haveone of the pin blocks 42independently adjustable with respect to its adjacent clamping oranchoring member 56 which is eifectedby substituting'for the: bolt 57,rod 60 having one end threadedly or loo otherwise secured to block 42slidably extending through clamping member 56 with its outer endpivotedly secured to cam lever,

' mounted on one of the winding pins L3, similar to trigger block 45heretofore described, and embodying an integral trigger mechanism 68positioned directly under face member 64 of body portion 65. A centerbore 66 extends through members 64, 63 and adapted to receive the pin 43when the said block is operatively positioned thereon, the operation ofthe trigger mechanism being similar to trigger blocks 45.

The reduced end'of body portion 65 is formed with an integral clampingor vice jaw 67 and is transversely or interiorly recessed, one side ofwhich is closed. by the detachable plate 68,, the said plate and theopposite side being apertnred to receive the adjusting screw 69 providedwith operating knob 70. Mounted on'said screw 69 within the said openingor recess isthe flanged nut 71 adapted to engage both sides of theadjustable clampingplate 72 slotted as at 73 and provided with handle 74by which it may be adjusted vertically. The nut 71 is internallythreaded to engage the threads 75 of the screw 69, so that by actuationof the said screw the plate 72 will move towards or away from the jaw67, gripping or releasing the lead wire or wires 59 as desired.

The other end of body portion 65 is constructed with a substantiallyyoke-shaped member 7 6 hinged to said body portion, as at 77 andcarrying screw 78 provided at its outer end with hand wheel 7 9 and itsinner end with clamp plate 80, the said yoke memher 7 6 being locked inoperative position by lock-pin 81 extending through the body portion 65and contacting with the under surface of the free end of the saidyol'zemember as at 82, the said screw 81 carrying coil spring 83 adaptedto hold the said pin in locked position when the yoke member 76 has beenbrought to operative position and the plate into clamping contact withthe lead wires 59, as clearly shown in Fig. 10 of the drawings.

lVith the types of winding heads heretofore employed it has beennecessary when commencing a loop to fasten the end of the .wire to somepart of the mechanism which had to be straightened and positioned toprovide a correct lead, with a consequent loss of time and materialwhich difficulties were materially increased when a plurality of wireswere simultaneonsly wound, and it was to overcome such deficiencies thatIdesigned the starting lead wire clamping mechanism above described.

From the foregoing it is apparent that I have designed a coil or loopwinding machine embodying many novel features in advance of those now inuse, of great adaptability, simple in construction, efficient for thepurposes intended, and the operation of which it is thought issufficiently clear from the above description to render furticrexplanation unnecessary.
